kaldkjede

Kaldkjede is the Norwegian term for the cold chain, a temperature-controlled supply chain that maintains products within defined temperature ranges from production to end user. It is essential for maintaining safety, quality, and regulatory compliance for perishable foods, pharmaceuticals, vaccines and other temperature-sensitive goods.

The kaldkjede comprises storage facilities, refrigerated transport, packaging, handling procedures, and documentation. Key elements include maintaining appropriate temperatures during storage, transit, and loading/unloading, as well as continuous temperature monitoring and traceability using data loggers, sensors and alarms.

Typical temperature ranges vary by product. Refrigerated goods are commonly kept around 2–8°C, frozen foods at approximately -18°C, while some medicines and vaccines require strict 2–8°C conditions or ultra-low temperatures. Temperature excursions, power outages or delays can compromise safety and quality, making robust logistics and contingency planning essential.

Regulatory and industry guidance for kaldkjede includes food safety management (HACCP/ISO 22000), Good Distribution Practice (GDP) for pharmaceuticals, and sector-specific vaccine cold-chain standards. Companies use calibrated equipment, validated processes, and documented records to demonstrate compliance and enable traceability.

Recent trends emphasize real-time monitoring, IoT-enabled sensors, improved insulation, and optimized routing to reduce losses and energy use. The term is widely used in Norwegian logistics, retail, healthcare and public health sectors.
